The craze for open-water swimming shows no sign of slowing down, with magazines, books and social media all offering countless glorious claims about its mental and physical health benefits.
The activity is known as 'wild swimming' (although to anyone who spent their childhood near open water, it will probably always be called simply 'swimming') and Ireland is blessed with almost innumerable places in which to do it.
One of these is Lough Swilly, between Inishowen and Fanad in Co Donegal. Swilly is one of only three glacial loughs in Ireland, the other two being Killary Harbour and Carlingford Lough. And as wild swimmers will confirm, it's "glacial" in more ways than one.
Those who prefer their bathing water temperatures firmly in double figures are bound to favour a heated swimming pool over an ice-cold lake. But the owners of this modern two-storey house at Carrownamaddy, near Burt, Co Donegal, have a choice. They're not much more than a mile from the shores of Lough Swilly, and they have an indoor swimming pool of their own.
The 8.3-metre pool is on the lower ground floor, along with changing room, shower and laundry room. Upstairs at entrance level there's a rather grand atrium with a double height-ceiling, a kitchen/ diner with patio doors, a triple-aspect lounge with a stone fireplace, and a TV room.
There's also one ensuite bedroom on this floor, and another three upstairs (two ensuite), along with a library with a secret door to a gallery above the lounge.
In all the floor are comes to 6,135 sq ft inside and it's on 2.54 acres with expired planning permission for two more houses.
Carrownamaddy is about four kilometres from the border and ten minutes' drive from Derry city.
It's for sale for €950,000 with Sherry FitzGerald Rainey (074) 912 2211.
